Hi
I have a Fedora installed and I try to generate my application's core dump file.
My system has no coredump limit:
$ ulimit
core file size (blocks, -c) unlimited
But when my application crashes no core dumps generated. I can generate dump file using gcore but it is not appropraite for my situation because it generates coredump file when I execute gcore, not when my application crahes.
Why can be the reason that my system doesn't allow coredumps to be generated? And how can I use gcore to generate coredump file when my app crashes?
Are you exceeding the the disk quota with your core dump? Are you blocking signals? What event (SIGBUS, SIGSEGV, etc)
causes the core dump event - if even you don't get a core file.
Code:
quota -v
will show you if quotas are enabled.
If your program calls chdir(), the core file will be in that new directory.
kill -SEGV <pid> gives me the core file for that process but also terminates the process.
Can I not get the core dump without terminating the process ? (2 Replies)
I'm working on a program in Linux with a group of people scattered around the country. When we have a crash, I like to send a core dump to the appropriate person so that they can understand the problem better. The problem is that our application uses several gigabytes worth of data and these... (4 Replies)
Hello,
I am debugging a program which works as daemon. It sigfaults, unfortunately I'm unable to generate core dump file. Here is what I am doing:
tsurko@bastila:~$ ulimit -c unlimited

i had a situation where a process was defunct. preap would not reap the process and gcore would not work properly (not sure why). therefore, the suggestion was to force a panic and collect the core dump. obviously you could do a savecore -L and capture the dump without bringing down the system....

My program is not dumping core when hitting a segmentation violation inside a thread.
However, it dumps core when the segv occurs within main.
Any ideas on how to diagnose this?

Hi,
Can we modify the GDB source code so as to analyze core dumps from different targets? From my analysis, I think we need to build our section table statically for each target. i.e., including the various address boundaries in build_section_table() function. If this is the case, then the GDB... (2 Replies)
hi everyone,
Right now when I do:
strcmp(s1, s2);
i get a core dump because at times s1 or s2 can be nothing so that makes strcmp() core dump.
What is the solution, if at times I expect one of them (or both) to be NULL?
I want to be able to compare that s1 is NULL and s2 is "blah" or... (6 Replies)
